Dacor Range, Oven, Cooktop Error Code LO

Despite appearing on Dacor cooking appliance documentation, the LO code is actually associated with the Dacor Millennia Dishwasher. It indicates that the rinse aid dispenser is low or empty. This is a routine maintenance alert and not a component failure. Refilling the rinse aid dispenser is the standard first step to address this code.

Running the dishwasher with low or no rinse aid is not a safety hazard, but it will likely affect performance. Without adequate rinse aid, dishes and glassware may come out with water spots, streaks, or poor drying results. It is best to refill the dispenser before running additional cycles to maintain optimal wash performance.

If the issue is simply a depleted rinse aid supply, the cost is minimal, typically just the price of a bottle of rinse aid, which generally runs in the range of a few dollars to around fifteen dollars. If the dispenser cap, sensor, or full dispenser assembly needs to be replaced, parts and labor costs will vary but could range from roughly thirty dollars to over one hundred fifty dollars depending on the specific component and whether a technician is needed.

Open the rinse aid dispenser located on the inside of the dishwasher door and refill it with a standard dishwasher rinse aid product up to the maximum fill line. Replace and secure the dispenser cap. Run a cycle to confirm the alert clears. If the LO code remains after refilling, inspect the dispenser cap seal and check whether the sensor or dispenser assembly may need to be replaced.

A simple power reset is unlikely to permanently clear the LO code if the rinse aid level is genuinely low, because the sensor will continue to detect the insufficient level and re-trigger the alert. The correct fix is to refill the rinse aid dispenser. Once the reservoir is adequately filled and the sensor reads a sufficient level, the code should clear on its own or after the next cycle.
